ALBERT JAHN, OF BERLIN, GERMANY.

PENHOLDER.

Specification of Letters Patent.

Patented Feb. 4, 1908.

Application filed November 9, 1906. Serial No- 342.626.

To all whom it may concern:

Be it known that I ALBERT JAHN, a citizen of the Empire of Germany, residing at Berlin, in the'Empire of Germany, have invented a new and useful Penholder, of which the following is a'spe cification.

The known penholders in general present the defect, that they are not shaped to suit the fingers of the writer and do not present sufficient and properly disposed faces for the fingers to easily and securely hold the, penholder. Thereby the correct position of the pen with regard to the paper'is rendered difficult to maintain. In consequence of this overstrains of certain muscles and nerves, premature weariness and .under circumstances even a writers cramp may be produced onthe one hand and an uneven and less beautiful writing may result on the other hand.v Beginners willfind' it diflicultf to learnwriting, sincethey have at the same time to learn the use of the penholder- My invention relates to im rovements in penholders,whereby the penho der is rendered easy to be taken hold of by the fingers of the writer and at the same time the learning of writing is facilitated. The new penholder is so shaped as to suit the fingers of the writer, more particularly his middle finger.

I will now proceed to describe my invention, reference being had to the accompanying drawings, in which Figure 1 is a side view of the new penholder and of three fingers holding the same, as looked at by the writer, Fig. 2 is a similar view of the penholder without the three fingers, Fig. 3 is a side view of the same seen from the other side, Fig. 4 is an end view of the same, Fig. 5 is a plan of the same, Fig. 6 is a bottom view of the same, Fig. 7 is a cross section through the same on the line 77 in Figs. 3 and 5, seen in the directions of the arrows, Fig. 8 is a cross section through the same on the line 88 in Figs. 3 and 5, seen in the direction of the arrows, Fig. 9 is a cross section through the same on the line 99 in Figs. 3 and 5, Fig. 10 is a side view similar to Fig. 1 and shows a modified penholder, Fig. 1 1 is a side view of the same penholder, seen from the other side, Fig. 12 is an end view of the same, Fig. 13 is a plan of the same, Fig.14 is a bottom viewof the same, Fig. 15 is a cross section through the same on the line 15-15 in Fig.

the direction of the arrows, Fig. 16 is a cross section through the same on the line 1616 in Fig. 13, seen in the direction of the arrows and Fig. 17 is across section through the same on the line 17 -17 in Fig. 13.

Similar characters of reference refer to similar parts throughout the several views.

The new penholder P is according to my invention provided with three faces t, f and m, so that its cross section through the line l 8 8 in Figs. 3 and 5 is substantially triangular, as is shown in Fig. 8. The'left face If is destined for the thumb T and is so shaped as to suit the latter. On the upper face f the forefinger F is to be placed, as is clearly shown 'in Fig. 1. In the plan of the penholder P (Fig. 5) the upper face f inclines from the longitudinal axis 11 to theleft' in accordance with the direction of the forefinger F.

The right face m is an essential feature of this invention and serves as a bearing for the middle finger M, which should bear against it comfortabl The cutting line ofthe face m with any p ane in the cross direction of the penholder A may be straight (see Figs. 7 and 8) and the cutting line of it with a plane passing through the longitudinal axis 11 of the penholder Amay be a slightly bent line or a straight line. The cutting line of the upper face f with any plane in the cross direction of the penholder A may be straight and the cutting line of it witha vertical plane passing through the longitudinal axis of the penholder A is a slightly curved line, which slopes towards the end'face e, in accordance with the natural position of the forefinger F,

see Fig. 1. The upper face f and the right face m are made to partly form a sharp edge 0, so as to enable the forefinger'F and the middle finger M to cooperate properly and closely. At theend face 6 the sharp edge 0 terminates in a oint on, which in plan of the penholder may e approximately in the center line 1-1 of the penholder P, as is shown .in Figs. 5 and 6. However, it isnotnecessary, that the point a: should be in the center line 1--1, it may be somewhere on either side of the latter. The clamping device 0 for the pen A maybe of any known eonstruction. For a straight pen A this clamping device 0 is preferably ine 1-1 0 the penholder P, so that in plan 13, seen in 1 (see Fig. 5) it is approximately in the d1reclaced at an angle to the center tion of the thumb T01 nearly so, While elevation (see Fig. 3) the pen A is made to modified in that the clamping device a is preferably placed parallel to itslongitudinal axis 1.'1 and that itisshiiped-aocordingly, as is shown at Figs. 10 to 17, which require no further explanations. Thef oint mis shown-as placed on'the left sideoi the longitudinal axis 11, see Fig. 13.

I claim:

A penholder havin on one side of the front 15 on the opposite side of the holder provided 20 with a clamping dex ioe for the pen. 5
